Sparkling XEN Technique: An Innovation in the Surgical Implantation Technique of the XEN Gel Stent Device

Fabrizio Franco, Federica Serino, Fabrizio Giansanti

The aim of this paper is to describe a modified technique of ab-interno implantation of the XEN gel stent. At the beginning of the surgery, the injection of 0.1 mL of air, and then of 0.1 mL of Balanced Salt Solution (BSS) in the subconjunctival space allows you to obtain a mechanical dissection between the conjunctiva and the Tenon’s capsule, transforming a virtual space in a real one. 23 eyes of 22 patients underwent the implantation of a XEN stent gel through the sparkling XEN technique. We retrospectively analyze the results with a reduction of the Intraocular Pressure (IOP) from an average of 16.9 ± 4.6 mmHg preoperatively to at 13.3 ± 1.4 mmHg at month 12. Needling was performed only in one case (4.34%). Two patients had hypotony (IOP<6 mmHg) at post-operative day 1, which self-solved, but we didn’t register any case of hypotony maculopathy and choroidal detachment. The gently dissection of the subconjunctival space performed with air and BSS makes the implantation easier and more predictable, consequently improving the surgical results, and at the same time preserve the tissue from excessive intraoperative handling.
